The present invention provides a document reading device capable of preventing erasure of printed information printed using erasable ink. A document reading unit (2) for reading printed information of documents, and a document feeding unit (3) for feeding documents placed on a document loading tray (31) to the document reading unit one by one , if a document reading instruction is accepted in a state where a plurality of documents are placed on the document loading tray, document reading in which one document is fed by the document feeding unit and read by the document reading unit is continuously performed. To operate, the original document reading device is equipped with: a temperature sensor that detects the temperature of the original document feeding path of the original document fed by the original document feeding section as the monitoring temperature T; The document reading control section suspends the document reading operation until the monitoring temperature T becomes lower than the recovery temperature threshold set below the suspension temperature threshold.
Description
technical field [0001] The present invention relates to a document reading device including a document feeding unit for feeding documents one by one, a document reading unit for reading the documents fed by the document feeding unit, and an image provided with the document reading device forming device. Background technique [0002] In recent years, a technique of printing information on recording paper using erasable ink that decolorizes at a predetermined temperature or higher (for example, 60° C. or higher) has been proposed. When the printed information printed using erasable ink becomes unnecessary, it can be erased by applying heat to the recording paper. Contents of the invention [0003] The problem to be solved by the invention [0004] However, in the prior art, there is a problem that the printed information printed with erasable ink is sometimes erased unintentionally when the document is read by the document feeding unit and the document reading unit, and ca...
